• How can I load a sql "dump" file into sql alchemy

  - by JudoWill

  I have a large sql dump file ... with multiple CREATE TABLE and INSERT INTO statements. Is there any way to load these all into a SQLAlchemy sqlite database at once. I plan to use the introspected ORM from sqlsoup after I've created the tables. However, when I use the engine.execute() method it complains: sqlite3.Warning: You can only execute one statement at a time. Is there a way to work around this issue. Perhaps splitting the file with a regexp or some kind of parser, but I don't know enough SQL to get all of the cases for the regexp. Any help would be greatly appreciated. Will EDIT: Since this seems important ... The dump file was created with a MySQL database and so it has quite a few commands/syntax that sqlite3 does not understand correctly.

• Cakephp with OpenID and User Authentication

  - by nolandark

  I have a table "users" and I want to enable my visitors to login with their openID Account. For this I use the OpenId Component for Cakephp and it works fine (When I login with the Google URL I receive the "successfully authenticated!" notification). But now I'm kind of stuck because I don't know how to go on from there. Do I have to create a User-Entry for every user which has a new entry in the "oid_associations" table (I save all OpenId interaction in the mysql database)? Do I have to authenticate the User after the login (or is the OpenID-component doing that automatically?). Am I completely misunderstanding the concept?

• How to organise a php based website

  - by bsandrabr

  I am putting my php /mysql website up and this is my scenario The users are grouped into sites each site with their own unique database. There will be about 40 users per site. the two options I'm trying to decide between are have a central website running the php and directing the users off to their own database using sub domains for each user each with their own php in htdocs I dont even know if 2 is possible/stupid but if it was, would it make any difference to performance as they're all being run by the same server. Any other ideas/ advice much appreciated as I want to organise it the best way from the start

• mysqli and field types

  - by Mikk

  Hi, I'd like to know if there is a simple way to fetch data from mysql tables with "correct" data types? What i mean, if field type is for example INT or SMALLINT is it possible to pass those types directly to PHP as integers? I did some searching and found mysqli_fetch_fields, but for SMALLIT type is 2, for INT 3 and so on. It could be done that way, but it looks rather clumsy workaround. Is there any better way? I'm using PHP and mysqli. Thank you.

• What ORMs work well with Scala?

  - by Clinton R. Nixon

  I'm about to write a Scala command-line application that relies on a MySQL database. I've been looking around for ORMs, and am having trouble finding one that will work well. The Lift ORM looks nice, but I'm not sure it can be decoupled from the entire Lift web framework. ActiveObjects also looks OK, but the author says that it may not work well with Scala. I'm not coming to Scala from Java, so I don't know all the options. Has anyone used an ORM with Scala, and if so, what did you use and how well did it work?

• .NET & ASP vs PHP

  - by gargantaun

  Earlier today I asked wether it would be a good idea to develop websites using C#. Most of the answers pointed towards .NET and ASP. Currently I develop with PHP. I've dabbled with Python and RoR but I always come back to PHP. This is the first time I've looked at .NET and ASP. A bucket load of Google searches later I'm not really seeing much support for ASP online but then it all seems a bit Biased towards PHP/Apache/MySQL. It looks like there's a fair amount of .NET and ASP folk around here so I figured it's worth a shot asking for their input in attempt to try and address the balance in my own head. It can't all be bad. What advantages are there to .NET and ASP over PHP?

• XAMPP mail not working with PHP mail() function.

  - by user296516

  Hi gusy, I just installed XAMPP, Apache is running, so is MySQL and Mercury. In Dreamweaver I created a php file with a mail($to,$subject,$msg,'From:'.$email); function, but when I ran the file from localhost it showed an error. After playing around with xampp control panel, turning mercury on and off, it's not showing any errors, yet is not send the email either... any ideas? the 'admin' button on the cp for mercury does nothing. Thanks! R

• how do i supply data to my gwt tree

  - by molleman

  Hello, So i need to create a tree with tree items for my gwt project. i am using the composite pattern to store all the information i need to be placed within a tree. A User has a root Folder that extends Hierarchy, this root Folder then has a list of Hierarchy objects, that can be FileLocations or Folders.

Also the tree item that i create would have to reference back to the object so i can rename or move it.

• Why is is giving me an SQL syntax error?

  - by Tibo

  Do you have any idea why i get this: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '``, `title` varchar(255) collate latin1_general_ci NOT NULL default ``,' at line 3 The code is like this (the part im having problem with...) $sql = 'CREATE TABLE `forum` ( `postid` bigint(20) NOT NULL auto_increment, `author` varchar(255) collate latin1_general_ci NOT NULL default ``, `title` varchar(255) collate latin1_general_ci NOT NULL default ``, `post` mediumtext collate latin1_general_ci NOT NULL, `showtime` varchar(255) collate latin1_general_ci NOT NULL default ``, `realtime` bigint(20) NOT NULL default `0`, `lastposter` varchar(255) collate latin1_general_ci NOT NULL default ``, `numreplies` bigint(20) NOT NULL default `0`, `parentid` bigint(20) NOT NULL default `0`, `lastrepliedto` bigint(20) NOT NULL default `0`, `author_avatar` varchar(30) collate latin1_general_ci NOT NULL default `default`, `type` varchar(2) collate latin1_general_ci NOT NULL default `1`, `stick` varchar(6) collate latin1_general_ci NOT NULL default `0`, `numtopics` bigint(20) NOT NULL default `0`, `cat` bigint(20) NOT NULL, PRIMARY KEY (`postid`) );'; mysql_query($sql,$con) or die(mysql_error()); Help would be greatly appreciated!

• Auto save changed text in richtextbox to database

  - by user2519407

  I have created one simple note taking application in jquery & php. Current functionality is like when user clicks save button it sends a ajax request with complete data to update it in db(mysql). All works well. But now I want to auto save only changed text while user typing. I don't want to send entire text to server again and again in text change event. It should send only text which has changed. For Ex: This is saved text. When user continues typing. This is saved text. Unsaved text.. It should be able to send only "Unsaved text.." to server to update in db. How can i implement this in jquery & server side script.? Any Idea..?

Does anybody knows how this is possible? edit: When I localy set this: ini_set('display_errors', 'on'); I do receive errors.

• PHP script for creating calendar table or jquery complete solution required

  - by finn_meister

  Ok so this is what I want to make: http://i44.tinypic.com/eiwphl.jpg red = booked green = available I have data in mysql in the format of: property_id, booked_from, booked_until . Before I start trying to create the correct loops etc to create and style the table, i thought i best ask if there are already good jquery plugins / php classes create this visual interface and uncluttered enough to allow me to add a select date range method (like Google Analytics)? I'm looking for something to create a basic calendar table on a loop, which i can then style and add jquery features. Though worth asking if there's a complete package that already does what i plan on making?!! (jquery ui's date-picker doesn't look powerful enough / easy enough to modify)

• Database design - alternatives for Entity Attribute Value (AEV)

  - by Bob

  Hi, see http://stackoverflow.com/questions/695752/product-table-many-kinds-of-product-each-product-has-many-parameters for similar topic. My question: i want to design a database, that will be used for a production facility of different types of products where each product has its own (number of) parameters. because i want the serial numbers to be in one tabel for overview purposes i have a problem with these different paraeters . One solution could be AEV, but it has its downsides, certainly because we have +- 5 products with every product +- 20.000 serial numbers (records). it looks a bit overkill to me... I just don't know how one could design a database so that you have an attribute in a mastertable that says: 'hey, you could find details of this record in THAT detail-table". 'in a way that you qould easely query the results) currenty i am using Visual Basic & Acces 2007. but i'm going to Visual Basic & MySQL. thanks for your help. Bob

• Folders-like URL with PHP?

  - by Maxime

  Hi, ever since I added this htaccess to my website, I noticed a HUGE slowdown, and my error logs are filled with errors such as PHP Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in page.php on line 79. I've got up to four of these per second. Most of the time it works though. The htaccess consisted of two similar rules: one with two GET vars, another one with only one. RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)\/(.*)$ index.php?var1=$1&var2=$2 [L] Anyway, I just rewrote a PHP script that handles of all the strings and redirects where it should, and my website is now fast again. But is there a way to hide mypage.php?var1=la&var2=lu and still have URLs that look like folders? Thanks for your replies!

• How to deal with 'bad' decision forced on you regarding basic software for your product

  - by raticulin

  Here is my situation, our product used to support several of the major databases. Now management has decided to move all products to MaxDB (aka SapDB previously), and even if we keep supporting some of the previous dbs, all new installations are on MaxDB. I am sure MaxDB is a great db and can support huge SAP installations. But from the point of view of a software developper, its a nightmare. Every time you need to do something not trivial (write an stored procedure, some fancy trigger...) and you google for some info, you get like 0.1% of the hits you would with things like MySql, PostgreSql or MSSql. Mailing lists are nearly non existant. SAP does support it commercially but it is not clear wether we'll buy support. And the decision cannot be rolled back. The product works with MaxDB, but with lots of inefficiency on development and a lot of frustration, is there something one could do?

• What some good PHP jobs?

  - by ggfan

  I am no professional PHP coder or anything, in fact I am fairly new. I can develop sites but nothing too crazy or fancy with PHP,Mysql,CSS,HTML,javascript. Up to now, all I have been doing is practice coding from books and websites. I am now looking for a 'real-life' experience. Besides going to a company and getting an interview, are there any other options in which I can get paid to code? I have posted some ads on craiglists but that's about it. And because this is my first time going to the 'real-word' and can make mistakes, am I liable if...a site I made for someone gets hacked and that person losses information?

• Best way to store chat messages and files

  - by Stnaire

  I would like to know what do you think about storing chat messages in a database? I need to be able to bind other stuff to them (like files, or contacts) and using a database is the best way I see for now. The same question comes for files, because they can be bound to chat messages, I have to store them in the database too.. With thousands of messages and files I wonder about performance drops and database size. What do you think considering I'm using PHP with MySQL/Doctrine?

• disabling transactional fixtures in Rspec has no effect

  - by Dia

  Due to a legacy database I'm using, I'm stuck with MySQL using MyISAM, which means my tables don't support transactions. This is causing the tests to fail, since table data generated (I'm using factory_girl for fixtures) by the tests are not reverted for each scenario. I discovered that Rspec exposes the config.use_transactional_fixtures config setting in spec_helper.rb. which is set to true by default. When I set it to false, I don't see any effect on my tests; they still fail due to duplicate records. Isn't that setting supposed to automatically unroll any changes made to the DB? Or am I supposed to do that manually?

• Building html tables from query data... faster?

  - by Andrew Heath

  With my limited experience/knowledge I am using the following structure to generate HTML tables on the fly from MySQL queries: $c = 0; $t = count($results); $table = '<table>'; while ($c < $t) { $table .= "<tr><td>$results[0]</td><td>$results[1]</td> (etc etc) </tr>"; ++$c; } $table .= '</table>'; this works, obviously. But for tables with 300+ rows there is a noticeable delay in pageload while the script builds the table. Currently the maximum results list is only about 1,100 rows, and the wait isn't long, but there's clearly a wait. Are there other methods for outputting an HTML table that are faster than my WHILE loop? (PHP only please...)

• Caching instances in a jee web app

  - by SibzTer

  Hi, Consider the scenario of a typical webapp with JSFs on the front and ejb3, with Hibernate as JPA provider, talking to backend database such as mysql, etc. The main user actions are login and mostly CRUD operations (minus any D(elete) operations). And the App Server is GlassFish of course. Given this scenario, how and where all would one go about providing caching to improve performance? From what I have googled, I have seen that hibernate provides some sort of caching through different cache providers. Is there any sort of caching that can be provided for the jsf pages? How about session beans or entity beans on the ejb side of things? Also, I just read about memcached and was wondering if this was something to consider?

• asp.net free webcontrol to display matrix reports with column and row grouping, subtotals and totals

  - by dev-cu

  Hello, I want to develop some kind of reports in Asp.net with x-axis and y-axis being dynamics, allowing grouping by row and column, for example: have products in y-axis and date in x-axis having in body number of sells of a given product in a given date, if date in x-axis are years, i want subtotals for each month for a product (row) and subtotals of sells of all products in date (column) I know there are products available to build reports, but i am using Mysql, so Reporting Service is not an option. It's not necessary for the client build additional reports, i think the simplest solution is having a control to display such information and not using crystal report (which is not free) or something more complex, i want to know if is there an available free control to reach my goal. Well, does anybody know a control or have a different idea, thanks in advance.

• Facelets charset problem

  - by Vladimir

  Hi! In my earlier post there was a problem with JSF charset handling, but also the other part of the problem was MySQL connection parameters for inserting data into db. The problem was solved. But, I migrated the same application from JSP to facelets and the same problem happened again. Characters from input fields are replaced when inserting to database (c is replaced with Ä), but data inserted into db from sql scripts with proper charset are displayed correctly. I'm still using registered filter and page templates are used with head meta tag as following: <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2"> If I insert into h:form tag the following attribute: acceptcharset="iso-8859-2" I get correct characters in Firefox, but not in IE7. Is there anything else I should do to make it work? Thanks in advance.

• What database is a good progression from MS Access for Coldfusion?

  - by Saul

  All my (home) CF learning has so far been done using Access as a database, and as far as the DB goes I "get it". There's no database server, and no need to log on to the database or anything, and setting up table relationships is easy and visual. Oh and its essentially free to deploy. However, I'm now working on an application that's likely to be used across several businesses and probably up to 50 concurrent users. I've heard that Access really isn't up to multi user use or production use on an app. What would you recommend as more suitable, preferably easy to grasp, with minimal tweeking needed for my SQL (I used a tool to convert to MySQL and it certainly handles concatenation differently, I dont want to have to do too much debugging), visual interface available, scalable, backupable, and whatever else I need that I don't yet know I need!
